This interesting surname derives from the Germanic personal name "Berto", a short form of the various compound given names with the element "berht" meaning bright or famous. The names Albert (noble-bright), Bertram (bright-raven), Bertrant (bright-shield), Gilbert (bright-pledge), Herbert (army-famous), Hubert (mind-bright), etc., have Bert as a pet form. The final "on" is a diminutive suffix, i.e., "little Bert", Berta (without surname) appears in the records of St. Benet of Holme, Norfolk (1101). One, Robertus Berte is noted in the Pipe Rolls of Sussex (1196). The form Berthon is French and is found with variant spelling Berton. Pierre, son of Jean and Magdalene Berthon, was christened at the church of Rumigny, Ardennes, France, on October 20th 1604. The name was introduced into England by French Huguenot refugees fleeing religious persecutions in their own country towards the end of the 17th Century. Madelaine, daughter of Michel and Jeanne Berthon, was christened on October 4th 1702, at the Artillery-French Huguenot Church, Spitalfields, London.
